2 Claims.

This invention relates to improvements in paper making and the principalobjects of the invention are directed to the method of providing paperwith a deckle edge or edges of a color contrasting with or differentfrom that of the main body of the paper.

According to special features of the invention the so-called coloreddeckle edge is provided on a web in connection with the papermakingoperation which results in economy in that it is not necessary toseparately handle the paper and the desired colored deckle edge effectis produced by reason of the particular condition of the In theaccompanying drawing:

Fig. 1 is a side elevational diagrammatic view of a portion of a papermaking machine to explain the novel features of the invention;

Fig. 2 is a plan view of a section of, a paper web to explain certainfeatures of the invention;

Fig. 3 is a sectional elevation on the line 3-3 of Fig. 2; and

Fig. 4 is a view similar to Fig. 2 to explain other features of theinvention.

According to the practise of the invention, paper making material isdelivered onto and carried by a carrier or forarm'nous making ele-. mentwhere considerable of the water is removed to form a web. As an example,the paper making material may be delivered onto a carrier such as aFourdrinier wire 2 or the same may be carried by a felt. As the carriertravels along in the direction of the arrow it supports the web of paperW.

At a point where the web W is substantially formed but somewhat moist,fibers are separated, displaced or removed at its edge or edges toproduce a deckled effect. In some cases it may also 40 be desirable toseparate, displace, or remove fibers longitudinally and intermediate theside edges of the web to provide separate webs which will have decklededges. .The fibers may be separated, displaced or removed in variousways as for instance by directing jets or streams of fluid onto the webso as to act on the fibers. In one way jets of water may be directedonto the web at its edge or edges in such a way that the fibers aredisplaced, separated, or removed 50 from the web W so that it has anuneven and more or less irregular and fuzzy marginal edge 1) or edgeswith the thickness increasing inwardly from the edge as shown in Figs. 2and 3. And a jet or jets may be directed onto the web 55 intermediateits edges whereby separate webs are provided which may have the uneven,irregular or fuzzy edges.

cated by 4 may be supported by a support member 6 disposed across thetraveling carrier supporting the web and located to deckle the edge oredges of the web and act on the central portion if desired. The relativedisposition of the nozzle or nozzles will determine the width of theseparate web or webs into which the main web is to be divided if it isdesired to separate the web into the narrower webs.

The nozzles will be connected to a source of fluid supply indicated by 8and by the means described the web as it travels therepast may beprovided with a deckle edge on either one or both marginal edges or theweb may be divided into a plurality of webs having deckle edges whichedges according to the invention are to receive color. To that end andpreferably adjacent the beforementioned nozzles for producing the deckleedges effect there is means for applying color to the said deckle edges.

Such means may include other nozzles such as ill or some suitable meansfor discharging a fiuicl or semi-fluid coloring substance which mayinclude dye or the like. These nozzles are preferablysupported by somemeans such as the support member I2 mentioned above and dispose inoperative relation to a suction device such as a suction box I4. As thecoloris discharged onto or applied to the deckled edge portion orportions, the action of the suction box is such as to tend to drawn thecolor into and through the deckled edge portion or portions whereby thesame becomes saturated or impregnated with the color.

The amount of color discharged may be varied or controlled by a valveIt, or in some way by varying the discharge orifice. To insure a uniformsupply of coloring material the same may be supplied by a conduit orconduits leading from a constant level supply tank 20 or the like.

As previously stated the formed web is more or less moist for thedeckling operation wherefor as the color is applied to the deckled edgeportion or portions D, which absorb the color or become saturatedthereby there is produced a colored deckle edge or edges D as shown inFig. 4.

As distinguished from a color stripe which would have a well definedmarginal edge or edges the color in this case is disposed on the deckleedge rather unevenly or non-uniformly by reason of the spreading orbleeding of the color to some extent andwhich is accounted for by the Anozzle or nozzles for the jets such as indimoisture content of the weband the way of applying the color.

It is possible therefor to provide an edge portion or portions for a webor webs which not only has the unevenness, featheriness; or fuzzinessthat characterizes a deckle edge but which is colored to enhance thedeckle effect and provide a new and pleasing effect with the said colorextending through the portion so that the web has the same color onopposite sides or it may vary if desired.

The color is dispersed more or less unevenly as described by reason ofthe moisture in the paper which is desirable and the bleeding orspreading of the color may be held within desired limits since it isapplied to the deckled edge when under the influence of the suctionwhich may be varied to bring about the desired saturation orimpregnation.

According to the invention it is possible to confine the color to thevicinity of the deckle edge portion or portions where it is desired,provide color at opposite sides of the web, and enhance the deckleeffect by the application of color.

While we have described the invention in great" detail and with respectto a preferred form thereof, it is not desired to be limited theretosince v many changes and modifications may. be made therein withoutdeparting from the spirit and scope of the invention. .What it isdesired to claim and secure by Letters Patent of the United States is:

1. The method of producing paper having a colored deckle-edge whichconsists in, moving a web of wet paper-making material of a certaincolor longitudinally on a paper-making element, removing some of thefibers of the paper making material from the web along its longitudinalside edges to provide deckle-edge portions which are of less thicknessthan the rest of the web and have irregular marginal edges, thenapplying liquid coloring material of a different color than saidpaper-making material to. said deckle-edge portions only of the webwhile the same is still moving and wet, and substantially simultaneouslywith the latter step subjecting said decide-edge portions to suction todraw said coloring material therethrough.

2. The method of producing paper having a colored deckle-edge whichconsists in, moving a web of wet paper-making material of a certaincolor longitudinally on a paper-makingelement,

while the same is still moving and wet, and substantially simultaneouslywith the latter step subjecting said deckle-edge portions to suction todraw said coloring material therethrough.
